Hi,

Is "Remove Black/White by Arctic Hunter" doing that or I should look for another filter? I think this filter was removing all white on black and white picture but now it is just not happening. Anything wrong or im not with the right filter?

Thnks.

i think there is another filter ( or maybe two more) about this same topic but I do not remember the name, sorry

i know it dis work, but not perfectly as it depends very much on the color range of the color you want to remove, as only will work perfectly if the source color to be removed is all the same color without variation

i did only test it a little, so I may be wrong

If by remove you mean turn into transparency (alpha), UnMultiply removes black and replaces it with alpha values:

You can invert an image so that all the whites are blacks, then run it through Unmultiply, then invert the image again, and I believe that will have the effect you want.
You refer to the prophecy of the pastry that will bring balance to the Force. And you believe it's this...donut?

You can use this snippet, inverting the result so that the color you pick is removed:
